Okay ladies (and men who like wearing jewelry), here comes a novel ring concept by Charles Windlin, which loosely reminds me of this bad boy. It's a ring watch that uses 1,400 metal balls to tell the time. Each ball has a decorative and magnetic side, and is electrically activated to show the appropriate side to either tell the time or display a message. The creator claims that the ring uses far less energy than an LCD display. You know what else uses far less energy than an LCD display? A sundial. Except when you have to use a flashlight to read it at night. Then you're using batteries.
